The beneficial effects lie in that by means of the apparatus, the collection of water samples at multiple pre-determined depths can be simultaneously realized in one instance of entering the water, thereby improving the usability of the apparatus; a protective cage (17) is arranged at an outer side of a collection cylinder main body (25), wherein the cage can not only protect the collection cylinder main body (25) but also effectively filter out impurities in a collected water sample; and the apparatus is easily operated and controlled, has good practicability, and can collect water samples at different depths.
